To all whom tt may concern y Be itknown that I, SAniu-:L OLSON, a citizen ot' the .United States of America, residing' at Chicago, in the county of 'Cook and State of Illinois-,have invented new and useful improvements' in Bread-Proofing Ap- -paratus, of which the following is a specification, reference being had to the accom,

paiiying drawings. forming a part thereof..

The purpose of this invention 1s toprovlde an improved system of a conveymg appara- 'tus' for use in the process oflprooting bread .interposed conveyer at the upper portion looking. in a Idirection transverse to the view of Fig. 1. .Figl 3 is a top plan view of the -parts. shown in Fig..1and showing also a portion-of theproofing conveyor. 4, 5 and 6. are detail views, respectively, of the three types of buckets composing the transferring coiivcyer. Figs. 7 and 8 are detail views. respectively, of the two types ot bucket. ends employed in the buclrets` shown in Figs. 4, 5 andA As is well understood by-those familiar with the art, it is'customary for thedough coming troin the dividing apparatus toho passed through a machine called the rounde'r-up whichl t'orms it into balls or loavesof uniform size, undfrom which it lsconvovcd veyer. which consists merely of arolulmratively `long convoyer chain provided with buckets or receptacles traveling slowly.

,usually in a serpentine path, in or through aroom Whose. tempei'aturc and humidity are such as to encourage the proper action in the loaves of dough. resulting in the desired dcgrec of lightness before they are put into an oven for baking is found. however. dough are passed di that when .the balls, o

.- rectly or allnost directly from thel rounder- 1 upinto the buckets .of the proofing couvever they are of such consistency as to he liable` to stick to the buckets of the 'onvcyer, after having-'rested therein for ten minutes orI some such time which constitutes the period 'of proofing; frequently, therefore, the con- "teuts of the buckets cannot b removed by merely inverting them and considerable time as well as a considerable amount. of dough is thus lost or Wasted. T0 avoid this diiiiculty the present invention provides-an intermediate convelyer .positioned'between the rounder up and t e proofing ccnveyer proper, so designed that from one-half to three-quarters of a minute is consumed in the travel of a' given bucket from the rounder-up to the point of discharge into the buckets of the proofing conveyer, and the time thus consumed issutiicient to effect the formation of a slightIl skin upon the loaves of dough which prevents them from adhering to the buckets of' the lproofing conveyer when transferred thereto, while the interval consumed in the" intermediate con-Veyer is not long enoughto permit the dough to`become stuck to the mentioned withrespect tov the proofing conveyor in which the dough remains for a much longer period of time. l

Referring to Fig. 1. of the drawi s, the rounder-up machine is indicated anni, and is shownprovided 'with a discharge chute, A1., from which the balls of dough are-de'- livered to 'a transferring drum, B, whose construction and operation are more particu.- .larly described in my Patent No. 1,038,784, dated September-17, 1912. The transferring drum, B, discharges the loaves or balls o1' they slide or roll by gravity into one of the buckets, C, of the intermediate or transferring c'onveyer. The direction of travei of these buckets when loaded is upward to the point at which the conveyer chains, C, pass around guide pulleys, C2. and are thus detiectt-d into a horizontal direction, and While traveling in this horizontal portion of their path tht` bucket-s, C, are dumped, discharging the doughjnto the buckets. D, of the }'r otiiig conveyer Whose position with respect to thepa'th of the buckets, C, is more clearly indicated in Fig. 2. Here it will b seen that while the buckets, C, are traveling horizontaily the buckets, D, are traveling vertically in a path laterally adjacent 1to that of the buckets. C. This requires the presence of guide inclines or chutes'E, which dotiert thebulls or loaves of `dough as'they 4 fall from the buckets, C, when thelatter are4 dumped, and discharge them into a `bucket buckets of this conveyer in the manner above.

do lgh on to a short incline, B1, from which vso lll() of theproong conveyer. To avoid excessive length in the proofing conveyer its bucketsare made long enough to hold 521761111 balls of dough,-as 1llustrated, they are designed for three loaves each so Ythat if each of the buckets, C, carries a single loaf a single bucket,D,ma be` filled -by simultaneously discharging t e contents of three of the buckets, C, into it. Fig. 1 shows three buckets, C", C, C, in dischar 'ng position,

- and illustrates` three guide c utes, E, ar-

ranged to deliver the doughinto theV pro er bucket, D, of the; proofing conveyer. he

' simultaneous dumping of the three buckets,

. conveycr chains,

.gIQups'pf three,the group, C", C', C'

. C", CY, C', is accom lished as follows The `fixed frame work, is provided'with three stops, Gx, Gy, G2, separated in the direction of travel of the Aconveyer by distances equal to those between successive buckets and positioned'two at oneside of the path of travel, 4and one at the other side, asindicated in .Fig 3. The buckets of the transferring ivotally hung -from the conveyer are all C, and are arran d in in typicalfftThe bucket, C,.is formed with "plainends; athebucket, Gy, has a lug or proj ectionl 'at'..one end adjacent to one. of the chains,fG,whi-le the bucket, C', is provided `with` a similar-'lug at the opposite end, that l is,-'djacent,to the other'of the chains, C.

The stopsor trips Gry and G', are of proper length to encounter, respectively, the projecting lugs ofy the'bucke'ts, Chaud C', but' do not extend farenough to enga eithe plain,

ends of the bucket, C, which wil therefore, passboth of these `stops without being `dumpedlby encounter therewith. Similarly the plain end ofthe bucket, Cf, will pass the stop, C, without eiect. But,.the trip, G, is enough longer than the step, to encounter the plain end ofthe bucket,l C?, causing it to -be inverted -in its travel an'dffthus to discharge its contents. Simultaneously the lugs or' projections ofthe buckets', C"

und Cz, will encounter, respectively, 'the trips, G and G, and. these buckets willbe similarly inverted, as indicated in Fig. 1. Obviously, the long trip, G, will effect the inversion of both buckets, CY' und C, as the pass it, but since-at that time they wil already have been emptied this feature is not objectionable. Asl above intimated, it is 'group being accesso modate two loaves, each of which is delivered simultaneously from a rounder-up of double capacity. This necessitates the v revision `of an extra set of discharge chutes, J1, whose'upper ends register substantially with the 'middle of the buckets, C, Vas they pass over the chu` and whose lower ends are positioned toy discharge into -a' secondv bucket, D, of the proofing conveyer, thus the capacity of` the plant is 'ust doubled since two buckets of the-proc ng conveyer are filled simultaneously each with three loaves which are discharged from' three buckets of the transferring conveyer. two loaves from each bucket.
